Restarting Webmin on Ubuntu: a Step-by-step Guide


Webmin is a powerful web-based control panel that allows you to manage various aspects of your Ubuntu server through a graphical interface. Occasionally, you may encounter issues or need to restart Webmin for various reasons. In this guide, we will walk you through the steps to restart Webmin on Ubuntu.

Step 1: Accessing the Terminal

  1. Launch a window for the Terminal application on your Ubuntu server. You may do this by simultaneously hitting the Ctrl, Alt, and T keys, or you can look for “Terminal” in the list of system apps.

Step 2: Logging in as Root

  1. To restart Webmin, you need administrative privileges. Log in as the root user by entering the following command in the Terminal:

sudo su

  1. When asked, enter the password for your user account. Take into consideration that the password won’t be seen as you input it.

Step 3: Checking Webmin Status

  1. Once you have root access, you can verify the status of the Webmin service by using the following command:

systemctl status webmin

  1. The output will show you Webmin’s current state at this moment. If it is already operational, you may go on to Step 5 without further consideration. Proceed to the next step if it is not running or if an error has occurred while it was running.

Step 4: Stopping Webmin

  1. To stop the Webmin service, enter the following command:

systemctl stop webmin

  1. This will halt the running instance of Webmin.

Step 5: Restarting Webmin

  1. To restart Webmin, execute the following command:

systemctl start webmin

  1. This will initiate a new instance of Webmin and make it accessible once again.

Step 6: Verifying Webmin Restart

  1. After you have restarted Webmin, you will be able to verify that it is operating normally without any problems. To determine the current state, use the following command:

systemctl status webmin

  1. The output should indicate that Webmin is active and running. If you encounter any errors, refer to the troubleshooting section or seek further assistance.

Step 7: Accessing Webmin

  1. After successfully restarting Webmin, the control panel may be accessed using a web browser on your computer. Launch the web browser of your choice on any of the devices that are connected to the same local network as your Ubuntu server.
  2. Enter the following URL in the address bar:


Replace “your_server_ip_address” with the actual IP address of your Ubuntu server.

  1. If you are accessing Webmin for the first time, your browser may display a security warning. Because Webmin utilizes a self-signed SSL certificate, this behavior is quite acceptable. Move on to the advanced choices and choose the option that says “proceed anyway” when you get there.
  1. On the login page, enter your administrative username and password for the Ubuntu server. These are the same credentials you used to log in as root earlier.
  2. Click on the “Sign in” or “Login” button to access the Webmin control panel.


Restarting Webmin on Ubuntu is a straightforward process that ensures the smooth operation of the control panel. You should be able to stop and start Webmin without any difficulty if you follow the step-by-step steps given in this article. This will enable you to easily manage your server using the web-based interface that Webmin provides.
